Has any one had success creating a ridgeline or earthen dam crest polyline feature class from a raster?

- I am trying to find the crest for 30 earthen dams (for now) from a raster.  I tried following trying to make it a stream and analyze it that way (... Extract elevation of ridge crest of a mountain range)  but did not have any luck.  The aspect spatial analyst tool will "show" where the crest is but still requires  some manual editing.


Has anyone found an good workflow to 'extract' the ridge line from a raster?


Thank you!
